Described as nice, honest, and hard working, Petra Martin took loving care of her 2-year-old son Uriel. As a toddler, Uriel was already a cancer survivor who had just finished a round of chemotherapy.

But on July 19, 2003, they were stabbed in what police say looked like a planned attack in their home in the 400 block of S. San Remo Avenue, between Cleveland and Court Streets.

Clearwater Police detectives spent several years sending away the same key piece of evidence for analysis: a bloody fingerprint found at the murder scene. Finally, last year, it came back with a match.

A judge issued two first-degree murder warrants for Gilberto Juarez-Hernandez. Police don't know what the motive or connection is between the victims and Juarez-Hernandez.

Juarez-Hernandez is 33 years old now.

According to records from a 1999 arrest in Iowa, he's described as 5 feet, 8 inches tall and 150 pounds. He has brown hair and brown eyes. Police say he has scars on his back, left hand, and one of his left fingers.

Detectives think he may be in Tampa Bay or in the Des Moines, Iowa area, where he has two brothers and several friends.
